Once you’ve spent some time with learning a CAM package, the complexity of the part should no longer be the limiter. The directory it’s in also includes pictures of machining the part: Here’s a pic of the most complex part I’ve created the g-codes for and machined, to go on a formula car: dxf export -> Rhino for tweaking -> Deskam to convert to G-codes -> DeskNC for G-code interpreting has worked well for me, for both a converted Bridgeport and my own desktop Sherline mill. I can’t afford the likes of Gibbs, FeatureCAM, and MasterCAM, although if I could or had access I would spend the time to learn them. I have mainly used Deskam, a hobby-level CAM program that does only 2 1/2-d parts, one toolpath at a time. I prefer to use CAM packages, but it doesn’t hurt to know the G-codes for hand-optimizing the larger programs and making tiny ones of your own. So everything I’m saying only refers to 2D designs (as far as I can say, anyway). I’ve used Z coordinates to specify the depths of the cuts, but not to create inclines or anything like that. b) Also keep in mind that I’ve really only ever done any of this in 2D.

Please keep in mind that a)It was only a year ago that I last did this, but that my retention span may be considerably shorter than that, feel free to correct me.

After you have the CADD drawing, it’s just a matter of setting a few options (most of which you would have to specify in your hand-written code anyway) and clicking OK. If it’s very complicated or large, you have to figure out which would be easier- finding the coords yourself or drawing it out in Inventor. If it’s a simple design, figure out the coordinates yourself. This may sound dumb, but I honestly think it comes down to whether or not its worth it to draw it out in a CADD program. It’s still a computer generated code that isn’t necessarily “smart.” However, unlike most of the HTML I’ve worked with, writing CNC code can get very, very tedious. CAM programs are basically WYSIWYG programs for CNC stuff. (This will be relevant, I swear.) I absolutely hate WYSIWYG programs. I’ve written my own G-code before (only simple stuff, basic lines, contours, and holes), and the hardest/most complicated part is figuring out exactly what the coordinates are. It was much easier for me to tell the CNC mill to make cuts from XYZ coordinates than to have MasterCAM do it. For example, I was using MasterCAM to make something for my Project Lead the Way “Computer Integrated Manufacturing” class, and I wanted to make an inclined-plane shape. However, I’ve found that it is often easier to write my own NC code for simple things. maybe.I don’t think there is any substitute for CAM packages like MasterCAM for advanced features like contours and such. I don't speak Java but I might have a look at doing some of this. PS: (I realize that laser engraving will need the S words more often, and possibly F as well, but ordinary routing definitely does not.)Īlso, the buffer size and timing issues apply to GRBL on an Arduino, on the upcoming ARM version it may not matter at all. G0 Z0 rapid down to surface - not the best idea but it does work ok for softer materials The S100 should be output when M3 is output as well, since some controllers will error or default to S0 so even though the spindle is enabled it will not be up to speed before the first cut starts.

(but Marlin will need a G1 or G0 on every line) Having such long lines can mean that GRBL cannot plan ahead efficiently because only a few actual lines fit in the buffer.

The other thing is the repetition of F1000 and S100 (and Z-3), and even the G1's, on every line.Īll those codes only need be output when they change since they are modal. so the initial 'go to start position should be at safe height rather than clearance height.Ĭode like this this would be much safer for initial positioning: I had my cutter positioned away from the cut area and while Z10 is safe within the cut area outside of that may have clamps or a vice etc. I was looking at the generated Gcode and noticed 2 things:
